Twin Engine: 1953 International Rat Rod

If you've got an old car with an inline-6 engine up front the easy route to making power is to replace it with an number of domestic V8s...but the easy way isn't the DT way...no sir...NOT EVEN A LITTLE BIT!  The DT way to do things is to take your non-crossflow inline-6 and add another engine side-by-side -- then connect the 12 cylinders with a Rube Goldberg set of pulleys/belts and burn rubber all the way to the bank.  Find this 1953 International Rat Rod here on eBay bidding for $5,000 reserve-not-met located in Pell City, AL with 3 days to go.

Twin Engine: 1954 GMC Semi Tractor

This has to be the strangest thing for sale on eBay right now, aside from Chia Pets that look like a human head, those things freak me the heck out.  Anyway, this next feature isn't freaky, but it has two huge inline-6 engines mounted up front.  Find this 1954 GMC Semi Tractor here on eBay bidding for $6,500 reserve-not-met with a few hours to go, located in Spokane, WA.

100+100=? 1970 Audi 100 Custom Twin Front

It never ceases to amaze me how busy people are when they post craigslist ads.  Sometimes folks on craigslist won't list the actual model name of their car, or neglect to list options, but today's seller doesn't even know the model year of this thing.  Actually...there is a good chance that this car contains two different vin numbers from two different cars, so the seller might be right to avoid any description of model year.  Find this 1970 Audi 100 Custom offered for $500 in Denton, NE. Tip from Andy.

5k: Occam's Razorback: 2000 Honda Prelude Twin Engine

The constant discussion of which is better, rear-wheel-drive or front-wheel-drive in slippery conditions is sort of ridiculous when you consider how much better all-wheel-drive can be.  Sort of like residents of San Diego and Los Angeles arguing that one eats more granola than the other when San Francisco is only a short drive north.  The problem with conventional all-wheel-drive is where to put the engine and how to distribute power when slippage occurs, so clearly the best solution for any traction issue is a twin engine car.  Sometimes the best solution isn't the most simple, but it is still the bestest.  Find this  2000 Honda Prelude Twin Engine here on eBay currently bidding for $6,100 reserve-not-met with 1 day to go, located in Brush Prairie, WA.  Tip from Rod.
